Gigabyte GA-P55-UD5 Motherboard Preview


Gigabyte GA-P55-UD5 Motherboard

Today, we have a sneak peak at the Gigabyte GA-P55-UD5 revision 0.2 motherboard for the upcoming Intel Core i5 processor series. This LGA1156 motherboard is part of the UD5 motherboard family, which means it features Gigabyte’s Ultra Durable 3 technology and the ‘5’ denotes that it should pack a hefty feature set.

Right off the bat you should notice that this board is based off of the LGA 1156 socket for Intel Lynfield CPUs, which has been rumored to be for both Core i5 and Core i7 processors, depending on the CPU features a particular model has. The upcoming Lynnfield processor supports dual channel memory only, so that is why you don’t see triple-channel memory support on P55 motherboards like the GA-P55-UD5 shown above.

Gigabyte GA-P55-UD5 Motherboard PCIe Slots

The Gigabyte GA-P55-UD5 Motherboard features three PCI-Express 2.0 x16 slots. Only the top two are powered by CPU the directly, offering either a single x16 link or two slots with eight lanes each. That means that the bottom slot will feature just four lanes that are channeled to the Intel P55 Express chipset and not directly to the CPU. For those that are worried about multi-GPU support it has been confirmed by Gigabyte that both ATI CrossFire and NVIDIA SLI are supported on the two main physical x16 slots from the CPU. In addition to the PCI-E slots, the GA-P55-UD5 features two PCI slots and two PCI-E x1 slots, although it appears that using a dual-slot graphics card will block the PCI-E x1 slot directly below primary x16 slot. You can also make out the board revision number in the image above, which is 0.2.

Gigabyte GA-P55-UD5 Motherboard DDR3 Memory Slots

The Gigabyte GA-P55-UD5 Motherboard has four dual-channel memory slots that can support up to 16GB of memory at 2000+ MHz/1333 MHz/1066 MHz/800MHz depending on if you are overclocking and what divider is being used. The board’s 24-pin ATX power supply header and IDE header can also be seen in the image above.

The rear I/O includes a PS2 keyboard or mouse port, ten USB 2.0 ports, both coaxial and optical S/PDIF out, two powered eSATA ports, two RJ45 sockets for Gigabit Ethernet, 6-pin and 4-pin Firewire sockets and six 3.5mm audio jacks providing the 7.1 channel surround sound as well as microphone and line-inputs.

Gigabyte GA-P55-UD5 Motherboard SATA Headers

The Gigabyte GA-P55-UD5 Motherboard has support for four SATA 6Gbps in RAID 0, 1 and six SATA 3Gbps in RAID 0, 1, 5, 10 on the board itself. If that is not enough storage space there are also two more SATA 3Gbps eSATA connectors on the board’s I/O backplane and one PATA header on the board itself. That means you can connect 12 SATA devices and 2 IDE devices on the Gigabyte GA-P55-UD5 Motherboard at the same time!
